This study was terminated on May 7, 2010 due to modification of the dimebon development plan, following the lack of demonstration of efficacy in the completed DIM14 (CONNECTION) Study. The study was not terminated due to any safety findings. Dimebon has been well-tolerated in clinical trials. Demonstration of efficacy for dimebon in Alzheimer's disease is pending completion of the ongoing DIM18 (CONCERT) Study.

Any major medical illness or unstable medical condition that may increase the risk associated with study participation or investigational product administration or may interfere with the ability to interpret study safety data
